Be it known that I; WALLACE E. WALDEN, a citizen of United States,residing at Domingo, in the'county of Sandoval, State of New Mexico,have invented certain new and useful Improvements in Feed Fuel forExplosion Engines; and I do hereby declare the following to be a full,clear, andexact description ofthe invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

T he object of the invention primarily is to provide a feed fuel meanswhereby the admission of moisture or of liquid fuel such as Funvaporized gasoline to the combustion chambers of the cylinders of themotor may be prevented, and hence specifically interpose an obstructionin the path of the film of liquid fuel due to deposit by condensation onthe walls of the, fuel feed tube, and which, due to the impulse of thevapor pass ing through the feed tube, tends to creep toward andultimately enter the cylinders where it is objectionable by reason ofcansing a carbon deposit through incomplete combustion; and furthermoreto provide a fuel feeding device for motors whereby an additional supplyof air may be introduced into the mixture adjacent to the point ofsupply of the fuel to the motor cylinders, and to construct such meansin the form of an attachment which may readily be applied to a motor ofthe conventional type without involving any modification in theconstruction thereof; and with these general objects in view, theinvention consists in a construction, combination and arrangement ofparts of which a typical embodiment is illustrated in the accompanyingdrawings, wherein:

Figure 1 is a sectional view of a motor fuel feeding tube, for conveyingmixture from the carburetor or other source of supply to the motorcylinders, equipped with a feed mechanism embodying the invention.

Figure 2 is a. section taken at right-angles to the plane of Figure 1.

Figure 3 is a detail view of the attachment embodying the inventiondetached from the feed tube.

Figures i and 5 are sectional views taken longitudinally and parallelwith the planes of the side surfaces of the attachment and viewing thesame respectively in opposite directions. V

Figure 6 is a detail sectional view on the plane of Figure 1, showingthe means where by the accumulation of liquid is removed.

The-device embodies a baffie 10' of annularform with a concaved surfacepresented to ward the direction of progress of fuel through the feedtube 11, used in the conventional type of internal combustion engines,preferably at a point near the junction of said feed tube with theintake manifold 12 of the motor, as for example, at the joint betweenthe feed or intake tube and said manifold, and this baffle may becarried by or formed as a part of a plate or gland 13, of dimensionscorresponding with the coupling plates 14 and 15, by which the feed orintake tube is attached to the intake manifold, for interpositionbetween said coupling plates as shown in Figures 1 and'2. so that theplate or gland 13 may be secured in position by the bolts 16 which areordinarily used to connect said coupling plates.

This b aille serves to obstruct or interrupt the passage along the wallsof the feed or intake tube toward the intake inanifcld of the film ofgasoline orother fuel which is deposited'in a condensed or liquid formupon said walls and which under ordinary conditions is caused to creeptoward the cylinders of the engine and ultimately enter the same byreason of the impulse due to i the passage of vapor consisting of themirture from the carburetor to the cylinders. The baflie serves tocollect this liquid and at the same time to restrict or reduce thepassage through the intake tube so as to increase the rap dity of theprogress of the mixture at that point, and hence increase the eiiiciencyor completeness of the lTllX- ture.

Taking advantage of the increased rapid- .7

ity of movement of the mixture at this point of reduction in the intaketube, it is also preferred to provide a means whereby an additionalsupply of atmospheric air may be combined with the mixture as a means ofeconomizing in the consumption of fuel, and to this end the plate orgland 13, which for convenience in reference may be described as a mixergland, is provided with a transverse channel 17 consisting in theconstruction illustrated of a tube arranged'in spanning relation withthe opening 18 in the gland and fitted at its e xtremitiesintransversely registering bores in the gland piate, with a jet opening ororifice 19 formed in the flway of a. minute orifice-23formed in the E2,a V V 1,464,592

" inner. wall thereof, .or in that wall facing the intake manifold andat or about the center of i the opening 18, and hence about in the planeof the annularQbaffie 10, where 'the vapor passes through the intaketube and attalnsj its highest velocity. One endof the conl veyor shouldbe closed as indicated at 20, :wh1le the other end in communication witha' channel 21 coredxin the mixer gland and extended to an inlet port, 22near one end thereof and within the contour of the gland, so as notvtobe obstructed by th'c arrangement of the coupling plates l l and 15,

which, are in contact with the opposite side 15 surfaces thereof; v r aIn practicethe baffle aswill be understood serves to interrupt anddirect lilie filfli of liquid fuel approach ng the motor cylinders andat thesame time acts as arreducer, while" :the-conveyor which isdisposed in spanning relation with the opening in the IHDZQY gland andwhich registers with the intake or feed u tube, affords a means ofsupplying an additional proportion of air to the mixer under theinfluence (of suction at the point of highest velocity/of mixturein itspassage to the motor: cylinders, with result of presenting thefinixturein economical proportionsand, in practically a dry'state to thecombustion chambers. V i

The accumulation of liquid fuel inter- V cepted' by the baflle l0 andcollected at the lower end of the tubular channel 17 is re movable-bysuction through the said tube by tube 17 in communication with thechamber formed by the concaved surface of the baffle, so'that the liquidfuel is drawn to the,

center of the tube. 17 through the air suction entering at 22 and isdischarged through the jet or opening 19 into the center of'the columnof vapor traversing the feedtube 11. The liquid accumulation; thereforeis discharged intothe column of gas approaching the, manifold and isatomizedto avoid disadvantages incident to the induction of liquid fuelinto theicylin ders has h'ereinbjefore explained.
